3. The two molecules shown below have the same number of carbon atoms. Which do you think will have the larger standard molar entropy? Choose one from the descriptions below. Hint: we did not specifically discuss this in class, but use your knowledge of "disorder" to choose the most sensible answer. You can also do further research on the web. n-hexane iii. iv. V. cyclohexane i. n-hexane, because it has more hydrogen atoms (C6H14) than cyclohexane (C6H12). ii. cyclohexane, because it has fewer hydrogen atoms than n-hexane. They are the same because they have the same number of carbon atoms. n-hexane because it is less rigid than cyclohexane. cyclohexane, because it is more rigid than n-hexane.

For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. System A few moles of carbon dioxide (CO₂) gas. A few grams of liquid ammonia (NH3). A few moles of carbon dioxide (CO₂) gas. Change The carbon dioxide expands from a volume of 10.0 L to a volume of 13.0 L while the temperature is held constant at 57.0 °C. The ammonia evaporates at a constant temperature of 11.0 °C. The carbon dioxide is cooled from 87.0 °C to -2.0 °C and is also expanded from a volume of 8.0 L to a volume of 11.0 L.

Try Again Your answer is wrong. • Second reaction: Your answer for A Sis incorrect. A chemical engineer is studying the two reactions shown in the table below. In each case, he fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 88.0 °C and constant total pressure. Then, he measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of his measurements are shown in the table. Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then, decide whether, under the conditions the engineer has set up, the reaction is spontaneous, the reverse reaction is spontaneous, or neither forward nor reverse reaction is spontaneous because the system is at equilibrium. 2Fe₂O3(s) 4Fe(s) + 30₂ (g) ΔΗ = 1648. kJ AS = 4631.

8. You have discovered a new polymer. A monomer is shown below. To better understand its behavior you calculate its theoretical entropy. With careful measurements you find that it can be in 3 positions around the 1st bond in the chain, 2 around the 2nd bond, 1 around the 3rd bond and 3 around the 4th bond. Further, the ring can be in 4 different positions. What is the entropy in units of KB?
